Artificial intelligence can do humanity a lot of good, but science fiction has made us paranoid about them starting to go rogue and harm humanity.

DeepMind, the AI company Google acquired in 2014 have teamed with scientists at the University of Oxford and published a paper that says AI should not be assumed it will "behave optimally all the time."

So to combat this, they would like all companies do tinker with AI to create a "big red button" that can be used to shut down the AI in case it starts to cause harm.
